d p ueau no teb r 19, 1949, Serial mk zas ie I My present invention relates to lubricating means for internal combustion engines and more particularly'to a novel top cylinder lubricator.

- The 'principal'object' of the present invention is topr ovide a device for continuous lubrication ofthe top cylinder area of an internal combustion'en'gine. 4

"Another object of the present invention is to provideia top cylinderi-lubricator which injects thelubricant directly into the intake manifold of the engine.

A further object of the present invention is to provide a top 'cylindeif lubricator which injects the lubricant intoithe top cylinder ofthe engine in the foringoi anatomized spray.

. Another object or the-presentinvention is t provide a top cylinder lubricator whichi's simple in construction and easy and economical to manufactureand assemble,

With the above and'other objects" and advantag'eous features in "view, my invention consists of a novel arrangement of parts, more fully dis- 1 Claim. (01. mar-.196)

All these methods, while helpful, are haphazard v and *inter'mittent. -To' insure an even and steady fiow or the lubricant areservoir is-clam'ped under the hood and a measured flow of 'oil fed to the intake manifold. The present invention comprises a refinement of this system by providing for an accurate visible control of the flow of oil and by providing an atomizin nozzle which atomizes the oil as it injects it into the manifold.

Referring'more in detail to the drawings illustrating'my invention, Figs. 1 and 2 show the general' arrangement of the device. The reservoir Ill is provided with the how control mechanism H and connected throughthe tube I2 and atomizingn'ozzle Iit-otheintake manifold 14. RB".

It has been" found that the introduction of a proper lubricant into thegas intake system of an engine serves to provide necessary lubrication for the top cylinder area. These lubricants are usually also provided with a carbon remover. The mixture thus keeps the top of the engine (valves, pistons and cylinders) free of carbon, properly lubricated and cooled. The easiest method used to introduce the lubricant is to pour it into the gasoline tank. However, the oil becomes diluted and this method provides only temporary lubrication. Other methods are pouring the oil directly into the top cylinder or pouring it through the carbureter.

plug ilfThe plug His provided witha central bore it andja screen filter l5 so that the air drawn into'thereservoir (as the oil is used up) isfiltered.

'Ifhe'fioWIcontrOl assembly I! is mounted on the cover, l5,a fitting .25 extending through the coverv l5 withj an'annular integral shoulder 2| resting" on topcf the cover [5 and heldv in, place by the threaded nut'ZZ beneath the cover. The oilfintakehornprises a'tube .23 depending from the fitting 25" and having a cone shaped .mem ber 24 atitslo'wer end. .A filter 25 is positioned in the member 2 to filter the oil passing up the tube. i f

The assembly mounted on top of the reservoir shown in Fig. 3 provides a visible adjustment of the oil fiow. Abiock 25 is mounted oni-the shoulder 2 iflof the fitting zii and is provided with the lateral threaded opening 21 to which the con nected tube I2 is attached. The opening 21 communicates with a .verticalopening 28 in the block. A suitable transparent housing 29 is mounted on the block 26 and is surmounted by a block 30. The block 39- is provided with a threaded opening 3| in alignment with the opening 28 in the block 21, and a depending spout 32 extending vertically through the block. A cover 33, slightly spaced from the block 36 surmounts the assembly. This assembly is held together by a tube 34 screwed into the fitting 20 and extending vertically through the opening 28 inthe block 26. The upper end of the tube 34 is screwed into a fitting 35 which extends downwardly through the cover 33 and is screwed into theopening 3| in the block 30. A manually operable needle valve 36 is mounted in the fitting 35 to control the flow from the top of the tube 34 through openings 31 in the fitting 35 and into the space between the cover 33 and block 30. 1

The oil will then flow down the spout 32, into the chamber 29, around the tube 34 into the openings 28 and 21 and then through the connecting tube l2. By. adjusting the valve 36, the number of drops per minute emerging from the spout 32 can be visibly adjusted to suit the operating conditions of each engine.

The atomizing nozzle 13, Fig. 4, comprises a block 38 having comparatively large bores 39 and 40 extending in alignment from each-end and connected by a small opening. Theconnecting tube [2 is threaded into the opening 39.

The bore 40 is provided with an offset-forming an outer bore portion '42 of slightly larger diameter than the bore 40. A tube 43 of the same diameter as the smaller portion of the bore 40. extends through the .bore 42 and is positioned tightly in the bore 40. The outer endof the tube 43 is provided with a narrowing conical shoulder-44. -A ballcheck valve 45 is pressed against'the opening 4| by a light spring 46 which rests against the conical portion 44 "in thev tube 43. This arrangement of the tube. leaves a narrow passage '41 surrounding the tube 43 at the wider passageway 42. This passage 41 communicates with an air intake..-passageway- 48 having a screenffilter 49. 1

The outer end of thetube 43extends into a threaded extended portion5fl of the block 38 anda ring, 51 is positionediin the end of the portion 50 to further restrict the terminus of the air passageway. The portion 5lis-screwe'd.

into the manifold connecting member 52,. Fig. 8, which is provided with a passageway 53 .communicating with the intake manifold. .The member '52 is generally flat and shaped to conform to the usual, intake manifold connection so that it 'canbe positioned there between the ends of the connection as shown in Fig. 2.

In operation, the suction vacuum created'by the engine will'open the check valve 45 and draw the measured quantity of lubricant from the connecting tube 12, opening 4 l through the'tube 43. Simultaneously, air will be pulled'int'o the opening 48 and throughlthe passageway 41, past the shoulder 44 and ring 5|. "The shape and restricted nature of this passageway causes the air to whirl violently and atomize the lubricant emerging from the end of the tube 43. The vaporized mixture then passes immediately through the passageway 53 into the intake manifold.

The advantages of the above construction are numerous. The flow of the lubricant can be visibly controlled at the reservoir and set for thebest operating efficiency for the particular engine. The atomized mixture passes immediately into the manifold intake so that it rtains its misty characteristic at the place where needed. Passage through long tubes causes condensation and loss of atomization. Further, it has been found that the device can be used as a water injector or for an alcohol and water injector to obtain increased power. Also, while the lubricant contains some carbon remover, in bad cases a pure carbon remover can be run through the device; with excellent results. The. atomization is so fine thatit has been found possible to put gasoline into the reservoir and to operate the device as an emergency carbureter when thegas line is clogged.

While I have described a specific embodiment of the invention, it is obvious that changes may readily be made in the size, shape, or relative arrangement of parts, without departing from the spirit and scope of the invention as defined in the appended claim.
